CALK FOR BOOTS OR SHOES.

SPECIFICATION forming part of Letters Patent No. 559,923, dated May 12,1896.

Application tiled llnly 19, 1895. Serial No. 556,544. (No model.)

L'o @ZZ whom, t may concern:

Be it known that I, JOSEPH ZANDALAZINI, a citizen of the United States,residing at Scranton, in the county of Lackawanna and State ofPennsylvania, have invented certain new and useful Improvements in Oalksfor Boots or Sliocs,of which the followingis aspecilication.

The pnrpose of this invention is to provide simple and effective meansfor securing antislipping and similar devices to boots and shoes,whereby the side wings or vertical extensions which engage with theedges of the sole can be adjusted to a greater or less disw lance apart,according to the size and last of the boot or shoe to which the deviceis to be attached.

The improvement consists of laterally-adjustable arms slidably connectedwith a soleplate, having their outer ends bent so as to engage with theedges of a sole, means for securing the arms to the plate and limitingthem in their movements, and a cleft spring having positive connectionwith the sole-plate and with the inner ends of the arms to automaticallyclamp the bent ends of the said arms against the edges of the sole, aswill appear more fully hereinafter.

The improvement also consists of certain details of construction andnovel combinations of the parts, which hereinafter will be moreparticularly set forth, illustrated7 and finally claimed.

For a full understanding of the merits and advantages of the inventionreference is to be had to the accompanying drawings and the following'description.

The improvement is susceptible of various changes in the form,proportion, and the minor details of construction without departing fromthe principle or sacrificing any of the advantages thereof, and to afull disclosure of the invention an adaptation thereof is shown in theaccompanying drawings, in which- Figure l is a side elevation of a shoehaving the invention applied. Fig. 2 is a detail view of the device.Fig. 3 is a transverse section on the line X X of Fig. Fig. et is adetail view of the arms and the spring-plate operatively connectedtherewith and disassociatcd from the sole-plate.

Corresponding and like parts are referred to in the followingdescription and indicated yallel slits.

in the several views of the drawings by the same reference-characters.

The invention is to be applied to an antislipping' or analogous device,which in its construction comprises a sole-plate l, and, as it will begenerally employed in connection with an antislipping attach1nent,theimprovement is illustrated in this connection. The heel-plate 2 has ashank portion which is hinged or pivotally connected to the soleplate,and suitable attaching-straps 3 are employed for connecting the deviceto the foot about as shown.

Loops 4 are provided near the edges of the sole-plate in transversealinement and are formed by depressing or punching a portion from thebody of the plate, the said depressed part being separated from the bodyby par- Arms 5 are slidably mounted in the loops et and have their outerends bent vertically, as shown at (5, and apertured to receive the strap7, which extends over the front portion of the foot. Headed studs Saroapplied to the inner ends of the arms and operate in transverse slots 9in the s0leplate, the slots and loops being in transverse alinement, soas to direct the arms in their movements. A springplate lO is cleft atits front end and is riveted or otherwise firmly attached at its rearend to theinner portion of the soleplate, and the front terminals of itsmembers are secured to the inner ends of the arms 5 and serve normallyto hold the arms in a retracted position. This spring-plate issufiiciently stout to cause the bent ends or vertical portions 6 of thearms to grip the edges of the sole and serves to center the attachmentwhen in position. The strap 7 supplements the action of the spring-platel0 and guards against accidental displacement of the device whenproperly applied to the foot. The operating parts are located on thelower side of the sole-plate, thereby preventing projecting portions onthe top side of the sole-plate and obviating annoyance, inconvenience,and possible injury.

Having thus described the invention, what is claimed as new is l. In anantislipping or similar device to be attached to a boot or shoe, thecombination with a sole-plate, of arms in transverse alinement andslidably connected with the IOO sole-plate, and having their outer endsbent vertically so as to engage with the edges of the sole7 anda'spring-plate rigidly secured at one end to the sole-plate and havingits front end cleft forming members Which are Secured to the said arms,substantially as shown for the purpose described.

2. The combination with a sole-plate having integral loopsnear its edgesin transverse alinement, of arms slidably mounted in the said loops, anda spring-plate havingits front end cleft forming members which aresecured to the inner ends of the arms, and having its opposite endattached in a positive manner to the sole-plate, substantially asdescribed.

3. In combination, a sole-plate having integral loops near its edges andtransverse slots in the same straight line, arms having their outer endsbent vertically to engage with the edges of a sole and having theirinner portions slidably mounted in the said loops, headed studs securedto the inner portions of the arms and operating in the transverse slotsof the sole-plate, and a springplate secured at its rear end to theinner portion of the sole-plate and having its front end cleft formingmembers which have positive connection With the inner ends of the saidarms, substantially as shown for the purpose described.
